In some PDF files , the hilghlighter and the underliner do not work , just the drawing mode and the T work, what should i do ? 

[Shagun Jain]

Can you please follow the following steps to use HighLight, Cut through(StrikeThrough) and Underline feature. This features are inside a tool called Commenting tool. There are 2 methods in which you can use this tool.

1. Entering commenting mode.
1. Open the pdf on which you want to use this tools.
2. Click on the blue colour button in bottom right corner of the screen. You will be presented with a list of options – “Comment”, “Fill & Sign”, Edit PDF and Organize pages.
3. Click on Comment option. You have entered commenting mode. In the bottom you will see a toolbar as shown in the attached Commenting.jpg file.
4. On selecting first button which looks like brush, highlighting operation will be selected
5. On selecting second button (T), Cut through (Strikethrough) operation will be selected
6. On selecting third button (T), Underline operation will be selected
2. On long press on text in the pdf.
1. Select the text on which you want to perform this operation by long pressing.
2. You will be shown with 4 options “Copy”, “Highlight”, “Strikethrough” and “Underline”.
3. On selecting any of these operation, you can complete your intended workflow.

I hope by following above steps you will be able to use these

Thanks,

Hi Shagun
I already knew all these steps , like I said earlier in some PDF files all
the tools in the toolbar work properly , and in some other files only the
drawing tool and ‘T’ work , the other thing is that I am using Acrobat on
my ipad , i see that you are a memeber of the Acrobat Android Team . Maybe
the app works differently on ios and android !?

Are there text in the document? Can you select text? Or is this a scanned document?

[Saman5CE8]

Yes , there is text in the document , actually it’s a book , and i am sure
that it is a PDF file , i can draw and add text into the file , but i
cannot highlight or underline !!
